Problems solved by technology
[0005] However, with the continuous improvement of low-cost and high-reliability requirements for new aircraft, parts and components are gradually becoming larger and more complex in structure. Traditional methods cannot manufacture such parts, and the existing single laser additive manufacturing technology is difficult to meet the manufacturing requirements.

Embodiment Construction
[0040] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.
[0041] Step 1: Use 3D drawing software (such as CATIA) to build a 3D digital model of large-scale complex structural parts, and use special repair software (such as MAGICS) to repair the 3D digital model;
[0042] Step 2: Use special repair software to cut the three-dimensional digital model of large-scale and complex structural parts into two three-dimensional digital models. The first digital model is suitable for precise and complex structures manufactured by laser selective melting forming tech...

Abstract
The invention discloses a method for additive manufacturing of metal parts with large-scale complex structures, comprising the following steps: establishing and cutting a three-dimensional digital model, manufacturing the first digital model part and manufacturing the second digital model part, first digital model Heat treatment of molded parts and the combination of second digital-analog parts, etc. The invention provides an additive manufacturing method for large-scale and complex-structure metal parts, which effectively combines laser selective melting forming technology and laser cladding technology to manufacture large-size and complex-structure metal parts that are difficult to manufacture traditionally, and solves many difficult problems. Manufactured parts with large size and complex structure, and greatly reduce the processing steps and shorten the processing cycle.
Description
technical field [0001] The invention relates to an additive manufacturing method for large-sized complex structural metal parts, belonging to the technical field of additive manufacturing. Background technique [0002] Additive manufacturing technology is a rapid prototyping technology based on the discrete-accumulation principle, driven by the three-dimensional data of parts, and using the method of accumulating materials layer by layer to manufacture solid parts. The biggest advantage of this forming method is that it can be formed without traditional tools, reducing the process and shortening the product manufacturing cycle. The more obvious the advantages, the broad application prospects in aerospace, biomedicine, energy chemical industry, micro-nano manufacturing and other fields. [0003] Additive manufacturing technology does not require molds, and can directly manufacture complex components at low cost, and is expected to further optimize the structure of existing a...
